Melvyn Bragg and guests discuss the period between the execution of Charles I in 1649 and the unexpected restoration of his son Charles II in 1660, known as The Interregnum. It was marked in England by an elusive pursuit of stability, with serious consequences in Scotland and notorious ones in Ireland. When Parliament executed Charles it had also killed Scotland and Ireland’s king, without their consent; Scotland immediately declared Charles II king of Britain, and Ireland too favoured Charles. In the interests of political and financial security, Parliament's forces, led by Oliver Cromwell, soon invaded Ireland and then turned to defeating Scotland. However, the improvised power structures in England did not last and Oliver Cromwell's death in 1658 was followed by the threat of anarchy. In England, Charles II had some success in overturning the changes of the 1650s but there were lasting consequences for Scotland and the notorious changes in Ireland were entrenched.

Melvyn Bragg and guests discuss the years of bloody conflict that saw Simon de Montfort (1205-65) become the most powerful man in England, with Henry III as his prisoner. With others, he had toppled Henry in 1258 in a secret, bloodless coup and established provisions for more parliaments with broader representation, for which he was later known as the Father of the House of Commons. When Henry III regained power in 1261, Simon de Montfort rallied forces for war, with victory at Lewes in 1264 and defeat and dismemberment in Evesham the year after. Although praised for supporting parliaments, he also earned a reputation for unleashing dark, violent forces in English politics and, infamously, his supporters murdered hundreds of Jewish people in London and elsewhere.

Melvyn Bragg and guests discuss the Roman poet Publius Ovidius Naso (43BC-17/18AD) who, as he described it, was destroyed by 'carmen et error', a poem and a mistake. His works have been preserved in greater number than any of the poets of his age, even Virgil, and have been among the most influential. The versions of many of the Greek and Roman myths we know today were his work, as told in his epic Metamorphoses and, together with his works on Love and the Art of Love, have inspired and disturbed readers from the time they were created. Despite being the most prominent poet in Augustan Rome at the time, he was exiled from Rome to Tomis on the Black Sea Coast where he remained until he died. It is thought that the 'carmen' that led to his exile was the Art of Love, Ars Amatoria, supposedly scandalising Augustus, but the 'error' was not disclosed.

Melvyn Bragg and guests discuss the treaties France entered into with the United States of America in 1778, to give open support to the USA in its revolutionary war against Britain and to promote French trade across the Atlantic. This alliance had profound consequences for all three. The French navy, in particular, played a decisive role in the Americans’ victory in their revolution, but the great cost of supporting this overseas war fell on French taxpayers, highlighting the need for reforms which in turn led to the French Revolution. Then, when France looked to its American ally for support in the new French revolutionary wars with Britain, Americans had to choose where their longer term interests lay, and they turned back from the France that had supported them to the Britain they had just been fighting, and France and the USA fell into undeclared war at sea.

Melvyn Bragg and guests discuss Laplace (1749-1827) who was a giant in the world of mathematics both before and after the French Revolution. He addressed one of the great questions of his age, raised but side-stepped by Newton: was the Solar System stable, or would the planets crash into the Sun, as it appeared Jupiter might, or even spin away like Saturn threatened to do? He advanced ideas on probability, long the preserve of card players, and expanded them out across science; he hypothesised why the planets rotate in the same direction; and he asked if the Universe was deterministic, so that if you knew everything about all the particles then you could predict the future. He also devised the metric system and reputedly came up with the name 'metre'.

Melvyn Bragg and guests discuss the conflict between Russia and Japan from February 1904 to September 1905, which gripped the world and had a profound impact on both countries. Wary of Russian domination of Korea, Japan attacked the Russian Fleet at Port Arthur and the ensuing war gave Russia a series of shocks, including the loss of their Baltic Fleet after a seven month voyage, which reverberated in the 1905 Revolution. Meanwhile Japan, victorious, advanced its goal of making Europe and America more wary in East Asia, combining rapid military modernisation and Samurai traditions when training its new peasant conscripts. The US-brokered peace failed to require Russia to make reparations, which became a cause of Japanese resentment towards the US.

Melvyn Bragg and guests discuss one of the most influential economists from the age of Adam Smith and Thomas Malthus. Ricardo (1772 -1823) reputedly made his fortune at the Battle of Waterloo, and he made his lasting impact with his ideas on free trade. At a time when nations preferred to be self-sufficient, to produce all their own food and manufacture their own goods, and to find markets for export rather than import, Ricardo argued for free trade even with rivals for the benefit of all. He contended that existing economic policy unduly favoured landlords above all others and needed to change, and that nations would be less likely to go to war with their trading partners if they were more reliant on each other. For the last two hundred years, Ricardo’s Theory of Comparative Advantage in support of free trade has been developed and reinterpreted by generations of economists across the political spectrum.

Melvyn Bragg and guests discuss the man who, according to Machiavelli, was the last of the Five Good Emperors. Marcus Aurelius, 121 to 180 AD, has long been known as a model of the philosopher king, a Stoic who, while on military campaigns, compiled ideas on how best to live his life, and how best to rule. These ideas became known as his Meditations, and they have been treasured by many as an insight into the mind of a Roman emperor, and an example of how to avoid the corruption of power in turbulent times.

Melvyn Bragg and guests discuss the plague that broke out in Constantinople 541AD, in the reign of Emperor Justinian. According to the historian Procopius, writing in Byzantium at the time, this was a plague by which the whole human race came near to being destroyed, embracing the whole world, and blighting the lives of all mankind. The bacterium behind the Black Death has since been found on human remains from that time, and the symptoms described were the same, and evidence of this plague has since been traced around the Mediterranean and from Syria to Britain and Ireland. The question of how devastating it truly was, though, is yet to be resolved.

Melvyn Bragg and guests discuss Chairman Mao and the revolt he led within his own party from 1966, setting communists against each other, to renew the revolution that he feared had become too bourgeois and to remove his enemies and rivals. Universities closed and the students formed Red Guard factions to attack the 'four olds' - old ideas, culture, habits and customs - and they also turned on each other, with mass violence on the streets and hundreds of thousands of deaths. Over a billion copies of Chairman Mao’s Little Red Book were printed to support his cult of personality, before Mao himself died in 1976 and the revolution came to an end.
